Advances in III-V based photonic crystals for integrated optical processing

ABSTRACT Compactness, massive integration of multiple functions on a single chip and power consumption are crucial fortransmission of large aggregated bit rates at short distance. Ecient implementation of data processing at theoptical level are very attracti ve. Here we present a technology for implementing ultra-fast switching with record-low energy ·recovery time product. We developed high-quality photonic crystal micro-resonators based on III-Vsemiconductors. The very short carrier lifetime of nano-pattened Gallium Arsenide enabled us to achieve 6 psrecovery time, thus enabling operations beyond the 100Gb/s rate. For broadband operation, highly nonlinearwaveguides with low insertion loss have been demonstrated.Keywords: Photonic Crystals, Integrated Optics, All-Optical-Processing 1. INTRODUCTION The viability of integrated optics for industrial-grade devices has now been demonstrated . The perspectiveon inter and intra-chip optical communication is also regarded as the potential solution for multi-core com-putation.
